Handheld Laser Cleaner Protects Cultural Relics

As an important and irreversible link in the process of cultural relics restoration, cultural relics cleaning not only requires a comprehensive understanding of the current situation of cultural relics preservation before starting the cleaning work, but also requires the selection of appropriate cleaning techniques. Laser cleaning equipment has incomparable advantages over traditional cleaning methods.

Traditional cleaning methods are quite limited. For example, the cleaning of the Avalokitesvara image. It occupies a cliff area of  88 square meters and an unfolded area of 220 square meters. It is connected to the mountain with various materials. The complexity of the environment and the technical difficulty required for restoration are much higher than the general cultural relics.

In order to adapt to the restoration work, the restoration engineers often stay in one position all day.. Due to the limitation of the cultural relics protection environment, air conditioners and ovens cannot be used.

Traditional cleaning methods include mechanical cleaning, chemical cleaning, and ultrasonic cleaning. There is a risk of residue and scratches on the surface of the utensils, and these cleaning methods are limited in terms of environmental protection and high precision requirements. For example, mechanical methods cannot meet the cleaning requirements of high cleanliness. Chemical cleaning methods easily cause environmental pollution, and the cleanliness is also limited. Although the ultrasonic cleaning method has a good cleaning effect, it is powerless to clean sub-micron particles. 

Laser cleaning equipment for cultural relics cleaning is a major advancement in the field of cultural relics protection and restoration.  The correct and safe laser operation can effectively protect the safety of people, cultural relics and the environment. Laser cleaning technology makes up for the shortcomings of traditional cleaning methods with its many advantages.

Laser cleaning is a non-contact cleaning method. The resonant cavity is used to gather light in the same direction, and has a simpler wavelength, better coordination and other performance, which can avoid secondary pollution to cultural relics.The correct and safe laser operation can effectively protect the safety of people, cultural relics and the environment. Laser cleaning technology makes up for the shortcomings of traditional cleaning methods with its many advantages.

Handheld laser cleaner has the advantages of easy control, easy automatic integration, no chemical reagents, surface cleaning,environmental protection, safety and reliability, and almost no damage to the substrate surface. It can solve many problems that cannot be solved by traditional cleaning.

With the continuous improvement of technology and the mass production of equipment, laser cleaning technology will play an important role in the cultural relics.
